Document Summary
During the pleistocene era, homo sapiens began to migrate out africa which marked the age of global human colonisation. Homo sapiens evolved near the african rift valley from the oligocene to the pleistocene and migrate north into europe and asia. By 18,000 years ago, humans reached the north easternmost area of asia and we able to cross the land bridge beringia, a land bridge that connected north america with northern asia. It is now covered by water and called the bering strait. Early north americans were of asian ancestry who lived in and migrated through siberia. These people were hunter-gathers and migrated to alaska by following herds of caribou or other game animals. The laurentide ice sheet influenced the migration pattern of the humans across the landscape. Theories include using an ice free corridor to migrate to the interior, people that built canoes to travel down the coast and others that waited for the glaciers to melt before migrating south.
